Here’s how you can use the Wiimote’s built-in accelerometers to measure your ride’s G forces and 0-60 time:

I got this idea after seeing some physics class use the wiimote in some kinda pendulum experiment.

Why not use the wiimote’s built in 3-axis accelerometers to measue g-forces, acceleration and even calculate my own 0-60mph times!

So I did. I wrote a script to dump all the g-force readings from the wiimote to a comma separated value file, then did some post processing in MS Excel, and voila, I can see every bump, every curve, my acceleration and braking, and even calculated my current speed using high school physics (v=a*t)

I wonder how much weight you could strip off this thing to get it to its bare essentials. A LiPo battery a gumstix board and maybe this could be extended to model rocketry or autonomous helicopter applications.
